Electron pairs precede high-temperature superconductivity
Like astronomers tweaking images to gain a more detailed glimpse of distant stars, physicists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory have found ways to sharpen images of the energy spectra in high-temperature superconductors - materials that carry electrical current effortlessly when cooled below a certain... view more...

New research shows EU how to hit Kyoto target
High temperature superconductor (HTS) devices could help the EU reduce its CO2 emissions by up to 52 million tonnes, equivalent to 65 per cent of its Kyoto Protocol commitment. Teemu Hartikainen, Jorma Lehtonen and Risto Mikkonen from Tampere University of Technology, Finland have worked out how much European GHG emissions would be reduced if... view more... (2003-07-23)
Powerful superconductor is in a class all its own
Superconductivity has perplexed, astounded and inspired scientists ever since it was discovered in 1911. Now, in the latest of a century of surprises, researchers at the National High Magnetic Field Laboratory at Florida State University have discovered unusual properties in a novel superconducting material that point to an entirely new kind of... view more...

Researchers explain odd oxygen bonding under pressure
Oxygen, the third most abundant element in the cosmos and essential to life on Earth, changes its forms dramatically under pressure transforming to a solid with spectacular colors. Eventually it becomes metallic and a superconductor. view more (2008-08-05)
Iron-arsenic superconductors in class of their own
Physicists at the U.S. Department of Energy's Ames Laboratory have experimentally demonstrated that the superconductivity mechanism in the recently-discovered iron-arsenide superconductors is unique compared to all other known classes of superconductors. view more (2009-04-30)
Newly discovered 'superinsulators' promise to transform materials research, electronics design
Superinsulation may sound like a marketing gimmick for a drafty attic or winter coat. But it is actually a newly discovered fundamental state of matter created by scientists at the U.S. Department of Energy's Argonne National Laboratory in collaboration with several European institutions. view more (2008-04-09)
For future superconductors, a little bit of lithium may do hydrogen a lot of good
Scientists have a long and unsuccessful history of attempting to convert hydrogen to a metal by squeezing it under incredibly high and steady pressures. view more (2009-10-06)
Scientists reveal effects of quantum 'traffic jam' in high-temperature superconductors
Scientists at the U.S. Department of Energy's Brookhaven National Laboratory, in collaboration with colleagues at Cornell University, Tokyo University, the University of California, Berkeley, and the University of Colorado, have uncovered the first experimental evidence for why the transition temperature of high-temperature superconductors -- the... view more...

Room temperature superconductivity
Scientists at the University of Cambridge have for the first time identified a key component to unravelling the mystery of room temperature superconductivity, according to a paper published in today's edition of the scientific journal Nature. view more (2008-07-10)
'Cooper pairs' can be found in insulators as well superconductors
Nearly a century ago, Dutch physicist Kamerlingh Onnes discovered that some metals transform into perfect electrical conductors when cooled to temperatures near absolute zero. Once started, their currents of electrons can flow perpetually. view more (2007-11-26)
UA Physicist Discovers Exotic Superconductivity
A University of Arizona physicist has discovered that powerful magnetic fields change the physical nature of superconductivity. view more (2006-08-17)
Physicists set 'speed limit' for future superconducting magnet
A research team led by a Northwestern University physicist has identified a high-temperature superconductor — Bi-2212, a compound containing bismuth — as a material that might be suitable for the new wires needed to one day build the most powerful superconducting magnet in the world, a 30 Tesla magnet. view more (2007-02-12)
Superconductivity can induce magnetism
When an electrical current passes through a wire it emanates heat - a principle that's found in toasters and incandescent light bulbs. view more (2008-09-12)
The first module of CMS superconducting magnet is leaving towards Cern: a huge solenoid, which will hold the world record of stored energy
The first module of the five constituting the CMS superconducting magnet is sailing on January 21st from Genova port to Cern. CMS (Compact Muon Solenoid) is one of the experiments that will take place at the accelerator Lhc (Large Hadron Collider), under construction at Cern in Geneva. The device will arrive after a 10-days travel. One of the most... view more... (2004-01-20)
Finding superconductors that can take the heat
Superconductors are materials with no electrical resistance that are used to make strong magnets and must be kept extremely cold-otherwise, they lose their superconducting abilities. view more (2005-11-09)
NIST micro sensor and micro fridge make cool pair
Researchers at the National Institute of Standards and Technology (NIST) have combined two tiny but powerful NIST inventions on a single microchip, a cryogenic sensor and a microrefrigerator. The combination offers the possibility of cheaper, simpler and faster precision analysis of materials such as semiconductors and stardust. view more (2008-04-16)
Delft nano-detector very promising for remote cosmic realms
A miniscule but super-sensitive sensor can help solve the mysteries of outer space. Cosmic radiation, which contains the terahertz frequencies that the sensors detect, offers astronomers important new information about the birth of star systems and planets. view more (2007-01-18)
Magnetism governs properties of iron-based superconductors
Though a year has passed since the discovery of a new family of high-temperature superconductors, a viable explanation for the iron-based materials' unusual properties remains elusive. But a team of scientists working at the National Institute of Standards and Technology (NIST) may be close to the answer. view more (2009-03-26)
Superconductivity: Which one of these is not like the other?
Superconductivity appears to rely on very different mechanisms in two varieties of iron-based superconductors. view more (2009-07-13)
UBC physicists develop 'impossible' technique to study and develop superconductors
A team of University of British Columbia researchers has developed a technique that controls the number of electrons on the surface of high-temperature superconductors, a procedure considered impossible for the past two decades. view more (2008-06-24)
